Copenhagen is holding the 19th edition of the LEN European Short Course Championships at the Royal Arena – the first, but probably not the last sports events at the new venue.

The capacity of the venue, which can typically hold 16,000, will be reduced to 6,500 as it finds room for the necessary 25-metre swimming pool.

More than 1,000 competitors from all over Europe are expected to compete over five days of competition, and 40 new European champions will be crowned. (EH)
